INSULATOR-SWITCH.

Specification of Letters Patent.

Patented July 10, 1917.

Application filed June 19, 1911. Serial No. 633,925.

To all whom it may concern.

I Be it known that I, CARL H. BIssELL, of Syracuse, in the county of Onondaga, in the State of New York, have invented a certain new and useful Insulator-Switch, of which the following is a specification.

This invention has for its object the production of an insulator switch, that is, a switch designed to be supported at the ends of insulators carried on poles or other structures and to which electric wires are connected; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a plan of one exemplification of my invention.

Fig. 2 is a side elevation partly in section of parts seen in Fig. 1.

Fig. 3 is a detail view partly in section of a portion of the clamping means and contiguous parts.

Fig. 4.2 is a fragmentary view showing my switch adapted to a different form of insulator from that shown in Figs. 1 and 2.

r 1 and 2 are a pair of insulators adapted to be mounted on a shank on a pole or on a building or any other structure. These insulators may be of any desirable form, size and construction, and those illustrated are for use with high tension circuits. Any other form of insulators may, however, be employed.

The switch comprises supports mounted on the insulators 1 and 2 respectively, a

' switch contact connected with one support and a movable switch arm associated with the other support and movable into and out of engagement with the contact.

3 and 4 are respectively supports in the form of disks or plates mounted on the ends of the insulators and resting against the contiguous end faces of the insulators and having means for securing the same to the insulators. 5 and 6 are blocks mounted on and fixed to the supports 3, 4:, the block 5 being provided with switch contacts 7 and the block 6 being formed with lugs 8 similar to the contacts 7 and to which the switch arm 9 is pivoted, as at 10, the switch arm being movable on its pivot'into and out of engagement with the contacts 7 The insulators 1, 2 are formed, respectively, with transverse grooves 11, 12 at their ends and the insulators are' so arranged that said grooves 11, 12 are in alinement; and each support 3 or 4 is provided with a transverse rib 13 for entering the groove 11 or 12 and detachably and directly engaging opposite walls of the groove and holding said support from displacement. Said supports 3, 4 are clamped to the insulators l, 2 by means entering circumferential grooves 14 formed in the insulators near the ends thereof.

in the illustrated embodiment of my invention each of the supports 3, 4: is formed with three arms, two of which, as 15, are provided with projections 16 at their ends for interlocking with the groove 1 and the third arm 17 of which carries clamping means for entering said groove 14. Said clamping means is here shown, Fig. 3, as a head 18 extending crosswise of its supporting arm and having parallel arms 19 on opposite sides thereof for sliding in grooves 20 on opposite sides of the arm 17, and a screw 21 threading through the arm 17 and bearing against the rear face of the head 18.

The blocks 5, 6- are secured to the supports in any suitable manner, as by screws 22, and each of the blocks is provided with means, as lugs 23, to which the wires can be attached.

This switch is articularly advantageous in that it can rea ily be secured to existing types of insulators, and in Figs. 1 and 2, standing insulators are shown, and in Fig. 4:, my switch is shown as adapted to a depending insulator, and means as a springpressed latch 24 is provided for holding the switch arm in its closed position.

What I claim is:

1. The combination with a pair of insulators each having a recess in its end face and a peripheral groove back of said face and a supporting member comprising aj plate resting against said end face and provided with a transverse projection extending into therecess for preventing relative turning movement of the insulator and the sulator, anda switch member secured to the outer face of one of said plates and switch jaws connected to the other of said plates, substantially as and for the purpose set forth. I

2. The combination with a pair of insulatorshaving transverse grooves at their ends, the groove of one insulator being alined with that of the other; of a switch comprising supports mounted on the insulators respectively and including plates having ribs extending into the alined grooves, each of said supporting members comprising means extending rearwardly relatively to the insulator from the supporting plate for clamping said supporting member to the insulator, a contact carried by one of the supports,

. and a movable switch arm carried by the other of the supports and movable into and out'of engagement with said contact, sub stantially as and for the purpose described.

3. The combination with an insulator having a peripheral groove, of a supporting member provided with a plurality of arms.

having projections cooperating with said groove, one of the arms having grooves in opposite sides thereof, and one of the proj ections consisting of a head extending crosswise of said one of the arms and having substantially parallel arms movable in the grooves in said one of the arms, and a screw extending through said one of the arms and coacting with the head for forcing said head into the peripheral groove, substantially as and for the purpose specified.

In testimony whereof, I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 3rd day of June, 19l1.

I CARL H. BISSELL.
